Yep, Bindweed is terrible stuff, but has a nice flower.
I was thinking those arrow-shaped leaves were part of it, but looking back, I see it isn't. Bindweed has smaller leaves that are reminiscent of a bean plant.
All Cacti are succulents, but not all succulents are Cacti
Chris and Daiv, thanks for the Bindweed Weed ID. All those pointed leaves in the first picture are those of the Bindweed plant. I really do like those flowers, and it's definately a low maintenance plant. Tony
